Lagos-Quintana et al. [1] reported the cloning of miR-1b, miR-1c and miR-1d. The mature processed miR sequences are identical apart from the 3' residues (A in mir-1b, C in mir-1c and UU in mir-1d). The 3' residues of both miR-1b and miR-1c conflict with the predicted stem-loop precursor sequence shown here and these sequences are not found in current assemblies of human and mouse genomes. It is suggested that polyA polymerase may add 1-3 nts to the 3' end of the mature transcript (Tom Tuschl, pers. comm.). The common 21 nts of the 3 reported miR sequences have been rationalised here and named miR-1. There are 2 pairs of orthologous putative hairpin precursor structures named mir-1-1 (human MI0000651, mouse MI0000139), and mir-1-2 (human MI0000437, mouse MI0000652). The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [2].
